  • Patent number: 10346214
    Abstract: Given a sequential resource allocation system (RAS) topology structure, a state space, called an impulse state space, corresponding to the impulse response of a linear time-invariant system (LTS), is computed by small enough configuration of the considered RAS. Given an initial resource configuration of a RAS which corresponds to an input of an LTS, a complete state enumeration can be obtained by defining the convolution of this configuration with the pre-computed impulse state space. One example embodiment reduces central processing unit (CPU) time to process instructions that compute a target state space of a RAS includes constructing an initial RAS and an initial state space, and extending the initial state space iteratively under a target resource configuration.

  • Patent number: 9927816
    Abstract: A method for operating a follower vehicle in a vehicle platoon includes determining, during operation, whether the follower vehicle is operating in a normal state or an abnormal state based on an operation condition of a component of the follower vehicle, or a communication between the follower vehicle and a preceding vehicle in the vehicle platoon. The method further includes selecting a first control mode if the follower vehicle is in the normal state and a second control mode if the follower vehicle is in the abnormal state so as to control movement of the follower vehicle using the selected control mode. In the first control mode, the follower vehicle uses communication data received from the preceding vehicle in the vehicle platoon to control its movement. In the second control mode, the follower vehicle uses data obtained by one or more of its sensors to control its movement.
